Description

Die Erfindung betrifft eine Vorrichtung zum Befestigen und Klemmen von Gurtbändern.The invention relates to a device for fastening and clamping webbings.

Gurtbänder (auch als Spanngurte bezeichnet) werden in vielen Bereichen verwendet, insbesondere zum Festspannen von zu transportierenden Gegenständen.Belt straps (also referred to as straps) are used in many areas, in particular for tightening objects to be transported.

Lange Gurtbänder oder auch Schlauchbänder mit Breiten von 25, 30, 35 oder 50 mm werden auch für die Sportart Slacklinen (Slacklen, Slacklining) verwendet, bei der man auf einem Gurtband balanciert, das zwischen zwei Befestigungspunkten gespannt ist. Das Gurtband wird an einem Ende mit einem Schraubkarabiner oder Schäkel befestigt. Am anderen Ende wird zum Spannen des Gurtbandes entweder ein Flaschenzug, wie man ihn aus dem Alpinismus kennt, eine Spanngurtratsche oder ein Hubzeug verwendet. Da sogenannte Longlines, welche teilweise über Distanzen von mehreren hundert Metern gespannt werden und Highlines, die in einigen Metern bis zu mehreren hundert Metern Höhe angebracht werden teilweise mit mehr als 15 kN vorgespannt werden müssen, damit man sie begehen kann, müssen die Klemmvorrichtungen hohe Bruchlasten aufweisen. Viele herkömmliche Klemmvorrichtungen sind für die Aufnahme entsprechender Kräfte nicht ausgelegt und beschädigen zudem das Gurtband, was zu einem Versagen desselben führen kann. Hinzu kommt, daß es erforderlich sein kann, die Klemmvorrichtung von dem Gurtband zu entfernen bzw. auf ein bereits gespanntes Gurtband aufzubringen. Dies ist mit den bekannten Klemmvorrichtungen nicht möglich.Long straps or even hose bands with widths of 25, 30, 35 or 50 mm are also used for the sport of slacklining (slacklining, slacklining), in which one balances on a strap that is stretched between two attachment points. The webbing is fastened at one end with a carabiner or shackle. At the other end is used to tension the belt either a pulley, as known from alpinism, a Spanngurtratsche or a hoist. Since so-called longlines, which are sometimes stretched over distances of several hundred meters and highlines that are mounted in a few meters up to several hundred meters in height must be partially biased with more than 15 kN, so you can commit them, the clamping devices have high breaking loads exhibit. Many conventional clamping devices are not designed to absorb such forces and also damage the webbing, which can lead to failure thereof. In addition, it may be necessary to remove the clamping device from the webbing or to apply it to an already strained webbing. This is not possible with the known clamping devices.

Aus der DE 1 773 606 U1 ist eine selbstschließende Parallelklemme zum Spannen von Drähten mit zwei symmetrischen Kniehebeln bekannt, bei der eine über einen Führungsstab angeordnete Druckfeder zwischen Zugbügel und dem die Klemmbacken tragenden Querstück angeordnet ist.From the DE 1 773 606 U1 is a self-closing parallel clamp for tensioning wires with two symmetrical toggle levers is known, in which a arranged on a guide rod compression spring between the clamping yoke and the jaws supporting crosspiece is arranged.

Die DE 30 38 418 A1 beschreibt eine Seil- oder Kabelklemme mit einem Paar von parallel zueinander geführten und verschiebbar in einem Gehäuse angeordneten, keilförmigen Klemmbacken, die gegebenenfalls durch Federbelastung in Klemmstellung gegen das Seil oder das Kabel gedrückt werden, wobei zum Lösen der Backen aus der Klemmstellung eine auf mindestens eine der Backen einwirkender Exzenter vorgesehen ist.The DE 30 38 418 A1 describes a cable or cable clamp with a pair of parallel and slidably arranged in a housing, wedge-shaped clamping jaws, which optionally by spring load in clamping position against the rope or the cable are pressed, wherein for releasing the jaws from the clamping position an eccentric acting on at least one of the jaws is provided.

Aus der DE 81 31 815 U1 ist eine Parallelklemme für Fernmelde-Freileitungen bekannt, bei welcher die einzuklemmende Freileitung, die auch aus einem blanken Draht bestehen kann, zwischen zwei sich beim Klemmvorgang aufeinander zu bewegenden Klemmbacken eingeklemmt wird. Dort wird ausgeführt, daß mit einer solchen Parallelklemme das Abspannen von beliebigen Drahtlängen oder Seillängen zwar leicht möglich ist, jedoch auf das abgespannte Seil bzw. den abgespannten Draht nicht beliebige Zugkräfte angelegt werden können, da sonst ein Gleiten des Drahtes oder Seils zwischen den Parallelklemmen erfolgt.From the DE 81 31 815 U1 is a parallel terminal for telecommunications overhead lines is known in which the clamped overhead line, which may also consist of a bare wire is clamped between two in the clamping operation towards each other moving jaws. There it is stated that with such a parallel clamp the clamping of any lengths of wire or pitches is indeed easily possible, but not any tensile forces can be applied to the guyed rope or the guyed wire, otherwise there is a sliding of the wire or rope between the parallel clamps ,

Die DE 89 01 065 U1 beschreibt eine Vorrichtung zum sicheren Festhalten eines band- oder streifenförmigen Materials, z.B. eines Flachkabels, an einer Montagefläche, wobei das band- oder streifenförmige Material im Innern der scharnierartigen Vorrichtung verklemmt wird.The DE 89 01 065 U1 describes a device for securely holding a band- or strip-shaped material, such as a flat cable, to a mounting surface, wherein the band or strip-shaped material is jammed inside the hinge-like device.

Aus der DE 10 2007 045 170 A1 ein Klemmschloß für ein Spannmittel bekannt, wobei in einem Gehäuse ein Anschlagsteg und eine Schwenkachse für ein Kammelement angeordnet sind.From the DE 10 2007 045 170 A1 a clamping lock for a clamping means known, wherein in a housing, a stop web and a pivot axis are arranged for a comb element.

Schließlich ist aus der WO 83/01433 A1 eine Vorrichtung zum Befestigen und Klemmen von Gurtbändern bekannt, die ein Paar Schwenkhebel aufweist, wobei zwischen den Schwenkhebeln zwei parallel zueinander angeordnete Klemmplatten und ein Keilelement mit ebenen Klemmflächen angeordnet sind.Finally, out of the WO 83/01433 A1 a device for fastening and clamping of straps known which comprises a pair of pivot levers, wherein between the pivot levers two mutually parallel clamping plates and a wedge element with flat clamping surfaces are arranged.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum Befestigen und Klemmen von Gurtbändern zu schaffen, die auch hohen mechanischen Beanspruchungen dauerhaft standhält und nicht zu Schädigungen des Gurtbandes führt.Object of the present invention is to provide a device for fastening and clamping of straps, which withstands high mechanical stresses permanently and does not lead to damage to the webbing.

Diese Aufgabe wird erfindungsgemäß für die Vorrichtung zum Befestigen und Klemmen von Gurtbändern dadurch gelöst, daß die Breite der Klemmflächen mindestens der Breite des Gurtbandes entspricht und daß Mittel zum Entfernen der Vorrichtung von dem gespannten Gurtband bzw. zum Aufbringen der Vorrichtung auf ein bereits gespanntes Gurtband vorgesehen sind.This object is achieved according to the device for fastening and clamping of straps, characterized in that the width of the clamping surfaces at least equal to the width of the webbing and that means for removing the device provided by the strained webbing or for applying the device to an already strained webbing are.

Die Schwenkhebel werden an einer Spannvorrichtung, beispielsweise einem Kettenzug, befestigt, bei dessen Betätigung die Schwenkhebel den Zug aufnehmen und diesen auf die Klemmplatten übertragen, so daß die Klemmplatten mit ihren Klemmflächen gegeneinander gepreßt werden, wodurch eine feste Klemmung des zwischen den Klemmflächen angeordneten Gurtbandes erfolgt.The pivot levers are attached to a tensioning device, such as a chain hoist, upon actuation of which the pivot levers absorb the tension and transmit it to the clamping plates, so that the clamping plates are pressed against each other with their clamping surfaces, whereby a firm clamping of the arranged between the clamping surfaces webbing takes place ,

Es kann erforderlich sein, die Klemmvorrichtung von dem gespannten Gurtband zu entfernen bzw. auf ein bereits gespanntes Gurtband aufzubringen. Dies kann beispielsweise durch Entfernen einer der Klemmplatten oder durch Entfernen eines Paars von Schwenkhebeln oder einer Kombination hiervon erfolgen.It may be necessary to remove the clamping device from the tensioned webbing or to apply it to an already strained webbing. This can be done for example by removing one of the clamping plates or by removing a pair of pivoting levers or a combination thereof.

Mit einer derartigen Vorrichtung, die auch den hohen mechanischen Beanspruchungen dauerhaft standhält, wie sie beispielsweise beim Spannen sehr langer Slacklines, sogenannten Longlines, auftreten, kann ein Gurtband sicher geklemmt werden, wobei mit zunehmender Spannung des Gurtbandes die Klemmung stärker wird. Das Gurtband wird auch bei wiederholtem Klemmen mit der erfindungsgemäßen Vorrichtung nicht beschädigt. Zudem ist die Vorrichtung einfach zu bedienen.With such a device that can withstand the high mechanical stresses permanently, as they occur, for example, when clamping very long slacklines, so-called longlines, a webbing can be clamped securely, with increasing tension of the webbing, the clamping is stronger. The webbing is not damaged even with repeated clamping with the device according to the invention. In addition, the device is easy to use.

Eine Weiterbildung der Erfindung besteht darin, daß eine Zuglasche vorgesehen ist, an der die Schwenkhebel angelenkt sind.A development of the invention is that a pull tab is provided on which the pivot levers are articulated.

Bei dieser Ausgestaltung wird die Zuglasche an der Spannvorrichtung befestigt und überträgt dann den Zug auf die Schwenkhebel und verhindert gleichzeitig das Wegkippen nach hinten der Vorrichtung unter Last.In this embodiment, the pull tab is attached to the tensioning device and then transmits the train on the pivot lever and at the same time prevents tilting backwards of the device under load.

Erfindungsgemäß ist vorgesehen, daß an einem der Schwenkhebel oder an der Zuglasche Befestigungsmittel angeordnet sind, welche das Befestigen einer Spannvorrichtung an der Vorrichtung erleichtern.According to the invention it is provided that on one of the pivot lever or on the pull tab fastening means are arranged, which facilitate the attachment of a tensioning device to the device.

Es liegt im Rahmen der Erfindung, daß die Befestigungsmittel als Haken, Öse, Gewinde oder Seilrolle ausgebildet sind.It is within the scope of the invention that the fastening means are designed as hook, eye, thread or pulley.

Eine Weiterbildung der Erfindung besteht darin, daß an jeder Seite der Klemmplatten ein Paar Schwenkhebel angeordnet ist.A development of the invention is that a pair of pivot levers is arranged on each side of the clamping plates.

Hierdurch wird die mechanische Belastbarkeit der Vorrichtung erhöht, da eine bessere Kraftübertragung von den Schwenkhebeln auf die Klemmplatten möglich ist.As a result, the mechanical strength of the device is increased, since a better power transmission from the pivoting levers on the clamping plates is possible.

Eine bevorzugte Ausbildung der Erfindung besteht darin, daß die Mittel zum Sichern des Gurtbandes im geklemmten Zustand als Auflage aus einem weicheren Material als das Gurtband, insbesondere einer Gummi- oder Kunststoffauflage, auf den Klemmplatten ausgebildet sind.A preferred embodiment of the invention is that the means for securing the webbing in the clamped state as a support of a softer material than the webbing, in particular a rubber or plastic pad, are formed on the clamping plates.

Hierdurch wird ein Herausgleiten des Gurtbandes aus den Klemmplatten verhindert.As a result, slipping out of the webbing is prevented from the clamping plates.

Es ist erfindungsgemäß vorgesehen, daß die Mittel zum Entfernen der Vorrichtung von dem gespannten Gurtband bzw. zum Aufbringen der Vorrichtung auf ein bereits gespanntes Gurtband als lösbare Befestigung einer der Klemmplatten oder eines Paares von Schwenkhebeln ausgebildet sind.It is inventively provided that the means for removing the device from the tensioned webbing or for applying the device to an already strained webbing are designed as releasable attachment of the clamping plates or a pair of pivoting levers.

Eine lösbare Klemmplatte kann beispielsweise mit Flügelmuttern an den Schwenkhebeln befestigt sein, die bei Bedarf gelöst werden können, um die Klemmplatte abzunehmen. Entsprechendes ist auch bei einem lösbaren Paar von Schwenkhebeln möglich.For example, a releasable clamping plate may be secured to the pivot levers with wing nuts, which may be loosened if necessary to remove the clamping plate. The same is possible even with a detachable pair of pivoting levers.

Alternativ oder in Kombination dazu kann auch vorgesehen sein, daß die Mittel zum Entfernen einer der Klemmplatten oder der Schwenkhebel als zu einer der Seiten hin offene Schlitze in den Schwenkhebeln zur Anlenkung der Klemmplatten ausgebildet sind.Alternatively or in combination, it can also be provided that the means for removing one of the clamping plates or the pivot lever are designed as slots open in the sides of the pivot levers for the articulation of the clamping plates.

Dies ermöglicht es, die Klemmplatte, ohne Verschraubungen lösen zu müssen, durch einfaches nach hinten klappen der Schwenkhebel zu entfernen.This makes it possible to remove the clamping plate without screwing, by simply folding back the pivot lever to remove.

Eine bevorzugte Ausführung der Erfindung besteht darin, daß der Abstand zwischen den Befestigungsmitteln an einem der Schwenkhebel bzw. dem Anlenkungspunkt an der Zuglasche und dem Anlenkungspunkt der diesem benachbarten Klemmplatte größer ist als der Abstand der Anlenkungspunkte der beiden Klemmplatten.A preferred embodiment of the invention is that the distance between the fastening means on one of the pivot lever or the articulation point on the pull tab and the articulation point of this adjacent clamping plate is greater than the distance of the articulation points of the two clamping plates.

Durch die Wahl des Abstandes zwischen den Anlenkungspunkten wird das Übersetzungsverhältnis bestimmt. Ein Übersetzungsverhältnis von 1 bis 1,5 hat sich als optimal verwiesen.By selecting the distance between the articulation points, the transmission ratio is determined. A gear ratio of 1 to 1.5 has been found to be optimal.

Nachfolgend werden Ausführungsbeispiele der Erfindung anhand von Zeichnungen erläutert.Hereinafter, embodiments of the invention will be explained with reference to drawings.

Die Vorrichtung gemäß Fig. 1 weist mindestens ein Paar zueinander parallele Schwenkhebel 3 auf, wobei zwischen den Schwenkhebeln 3 zwei parallel zueinander angeordnete Klemmplatten 4 mit ebenen Klemmflächen 5 angelenkt sind. Vorzugsweise-ist an jeder Seite der Klemmplatten 4 ein Paar Schwenkhebel 3 angeordnet, um eine gleichmäßige Kraftableitung sicherzustellen.The device according to Fig. 1 has at least one pair of mutually parallel pivoting lever 3, wherein between the pivoting levers 3 two mutually parallel clamping plates 4 are articulated with flat clamping surfaces 5. Preferably, a pair of pivoting levers 3 are arranged on each side of the clamping plates 4 in order to ensure a uniform force discharge.

Die Breite der Klemmflächen 5 entspricht mindestens der Breite des jeweiligen Gurtbandes 6. Die Klemmplatten 4 sind mit Mitteln 7 zum Sichern des Gurtbandes 6 im geklemmten Zustand versehen, die beispielsweise als Gummi- oder Kunststoffauflage 7 die Klemmflächen 5 bilden.The width of the clamping surfaces 5 corresponds at least to the width of the respective webbing 6. The clamping plates 4 are provided with means 7 for securing the webbing 6 in the clamped state, which form the clamping surfaces 5, for example as a rubber or plastic pad 7.

Ein Paar der Schwenkhebel 3 weist an seinem freien Ende eine Befestigungsvorrichtung 2 zum Befestigen einer Spannvorrichtung an der Vorrichtung auf. Die Befestigungsmittel 2 sind hier als Querbolzen zwischen den freien Enden des Schwenkhebelpaares oder als Öse 2 an einem Ende der Zuglasche 1 ausgebildet, wobei auch andere Formen, beispielsweise als Haken, als Innengewinde, als Gewindebolzen oder als Seilrolle möglich sind. Mit diesen Befestigungsmitteln 2 kann die Vorrichtung beispielsweise an einem Kettenzug befestigt werden oder als sogenannte lose Rolle in einen Flaschenzug integriert werden.A pair of pivot levers 3 has at its free end a fastening device 2 for attaching a tensioning device to the device. The fastening means 2 are formed here as a transverse bolt between the free ends of the pivot lever pair or as an eyelet 2 at one end of the pull tab 1, whereby other shapes, such as hooks, as internal threads, as threaded bolts or pulley are possible. With these attachment means 2, the device can for example be attached to a chain hoist or integrated as a so-called loose role in a pulley.

Wenn auf die Befestigungsvorrichtung über das Befestigungsmittel 2 Zug ausgeübt wird, werden die Schwenkhebel 3 umgelenkt und die Klemmplatten 4 mit ihren Klemmflächen 5 gegeneinander gepreßt, wodurch eine feste Klemmung des Gurtbandes 6 in der Vorrichtung erfolgt und der Zug auf das Gurtband 6 übertragen wird.If train is applied to the fastening device via the fastening means 2, the pivot lever 3 are deflected and the clamping plates 4 pressed against each other with their clamping surfaces 5, whereby a firm clamping of the webbing 6 takes place in the device and the train is transmitted to the webbing 6.

Weiterhin sind Mittel 9 zum Entfernen der Vorrichtung von dem gespannten Gurtband 6 bzw. zum Aufbringen der Vorrichtung auf ein bereits gespanntes Gurtband 6 vorgesehen, die als lösbare Befestigung der oberen Klemmplatte 4 ausgebildet sein können, welche sich durch die Schwenkhebel 3 und die obere Klemmplatte 4 erstreckt. Während die untere Klemmplatte 4 mit den Schwenkhebeln 3 vernietet oder unlösbar verschraubt ist, kann die obere Klemmplatte 4 beispielsweise Flügelmuttern aufweisen, die ein Entfernen des Befestigungselementes, das die Schwenkhebel 3 mit den Klemmplatten 4 verbindet, ermöglichen. Gerade auch in Kombination mit einer lösbaren Verschraubung der Klemmplatten 4 können als Mittel zum Entfernen einer der Klemmplatten 4 zu einer der Seiten hin schräg angeordnete offene Schlitze 9 in den Schwenkhebeln 3 ausgebildet sein, die ein Entfernen von Befestigungselementen entbehrlich macht, da durch vorklappen der Schwenkhebel die obere Klemmplatte 4, welche in diesem Fall Bolzen als Anlenkungspunkte 8 beherberg, entfernt werden kann. Entsprechend ist es auch möglich, zum Entfernen der Vorrichtung von dem gespannten Gurtband 6 bzw. zum Aufbringen der Vorrichtung auf ein bereits gespanntes Gurtband 6 ein Paar Schwenkhebel 3 lösbar auszugestalten.Furthermore, means 9 are provided for removing the device from the tensioned webbing 6 and for applying the device to an already tensioned webbing 6, which may be formed as a releasable attachment of the upper clamping plate 4, which is defined by the pivot lever 3 and the upper clamping plate. 4 extends. While the lower clamping plate 4 is riveted or unsolvable bolted to the pivot levers 3, the upper clamping plate 4, for example, have wing nuts, which allow removal of the fastener connecting the pivot lever 3 with the clamping plates 4. Especially in combination with a releasable screwing of the clamping plates 4 may be formed as means for removing one of the clamping plates 4 to one of the sides obliquely arranged open slots 9 in the pivoting levers 3, which makes it unnecessary to remove fasteners, as by folding the pivot lever the upper clamping plate 4, which in this case accommodates bolts as articulation points 8, can be removed. Accordingly, it is also possible to detachably detach the device from the tensioned webbing 6 or to apply the device to an already tensioned webbing 6 a pair of pivot levers 3.

Aus Fig. 1 ist weiterhin zu ersehen, daß der Abstand A zwischen dem Befestigungsmittel 2 und dem Anlenkungspunkt 8 der diesem benachbarten Klemmplatte 4 größer ist als der Abstand B der Anlenkungspunkte 8 der beiden Klemmplatten 4 (vorzugsweise ist A das 1 bis 1,5-fache von B). Dieser Abstand entspricht dem Übersetzungsverhältnis der Vorrichtung.Out Fig. 1 It can also be seen that the distance A between the attachment means 2 and the articulation point 8 of the adjacent clamping plate 4 is greater than the distance B of the articulation points 8 of the two clamping plates 4 (preferably A is 1 to 1.5 times B) , This distance corresponds to the transmission ratio of the device.

Die Fig. 2 zeigt eine Weiterbildung dieser Vorrichtung, bei der gleiche Teile mit gleichen Bezugszeichen versehen sind wie in Fig. 1. Diese weist eine beispielsweise als gebogenes Metallteil ausgebildete Zuglasche 1 auf, an deren freiem Ende die Befestigungsmittel 2 angeordnet sind. An dieser Zuglasche 1 sind die Schwenkhebel 3 angelenkt. Um ein Wegknicken nach hinten unter Last zu verhindern, wird eine Stützfläche 10 angebracht, welche das Knickmoment der Klemmplatten 4 auf die Zuglasche 1 überträgt und somit mindert.The Fig. 2 shows a development of this device, in which the same parts are provided with the same reference numerals as in Fig. 1 , This has a trained example as a bent metal part pull tab 1, at the free end of the fastening means 2 are arranged. At this pull tab 1, the pivot lever 3 are hinged. In order to prevent buckling back under load, a support surface 10 is attached, which transmits the bending moment of the clamping plates 4 on the pull tab 1 and thus reduces.

Aus Fig. 2 ist weiterhin zu ersehen, daß der Abstand A zwischen dem Anlenkungspunkt 8 der Zuglasche 1 und dem Anlenkungspunkt 8 der diesem benachbarten Klemmplatte 4 größer ist als der Abstand B der Anlenkungspunkte 8 der beiden Klemmplatten 4 (vorzugsweise ist A das 1- bis 1,5-fache von B). Dieser Abstand entspricht dem Übersetzungsverhältnis der Vorrichtung.Out Fig. 2 It can also be seen that the distance A between the articulation point 8 of the pull tab 1 and the articulation point 8 of this adjacent clamping plate 4 is greater than the distance B of the articulation points 8 of the two clamping plates 4 (preferably, A is the 1- to 1.5- times of B). This distance corresponds to the transmission ratio of the device.
